Description
Technical Field
[0001] This invention relates to the field of steel cage transportation technology, and more specifically, to a steel cage transportation device for steep mountainous terrain. Background Technology
[0002] Concrete is characterized by extremely high compressive strength but extremely low tensile strength. Steel reinforcement, on the other hand, has extremely high tensile strength. A steel reinforcement cage is a composite material made by weaving steel bars into a cage-like structure and combining them with concrete, creating a complementary composite material that can withstand various complex forces in engineering structures.
[0003] In some remote areas, when carrying out infrastructure projects, steel reinforcement cages are required to be centrally processed and then transported to the site for installation. However, in remote mountainous areas, due to the steep terrain, it is difficult to build access roads, and the roads are very narrow with many sharp bends. If the steel reinforcement cages are long, transporting them by vehicle presents several problems, such as insufficient turning radius, lack of U-turn space, vehicle width exceeding road width, and damage to the steel reinforcement cages.
[0004] Existing technologies allow for the segmentation and disassembly of reinforcing cages, followed by welding or connecting components, thereby reducing the length of the cage during transport and facilitating the passage of transport equipment through narrow, rugged, and undulating areas. However, in conventional manual welding of reinforcing cages, although calculations are made to ensure that the joint positions avoid areas of maximum stress, the welding conditions are limited due to the need for fieldwork in mountainous areas. In particular, the alignment process during welding is challenging because the lack of equipment capable of externally driving the reinforcing cage results in poor alignment of the vertical bars, affecting the welding fixation effect. Summary of the Invention
[0005] To address the aforementioned problems, this invention provides a steel cage transportation device for steep mountainous terrain, which is a transportation device specifically designed for storing, fixing, aligning, and welding integrated steel cage segments in steep mountainous terrain.
[0006] This invention is achieved through the following technical solution: a steel cage transportation device for steep mountain terrain, comprising a vehicle body, a cargo box on the vehicle body, and the cargo box for storing several steel cage segments;
[0007] Several fasteners are provided inside the cargo box along the width of the cargo box. The fasteners are used to fix the steel cage section. Guide rails are fixedly connected to both sides of the top inside the cargo box. A crossbeam is slidably connected on the guide rail. A first driving component is provided on the guide rail for driving the crossbeam to slide. A slider is slidably connected on the crossbeam. A second driving component is provided on the crossbeam for driving the slider to slide. An operating arm is provided at the bottom of the slider. A clamping claw is fixedly connected to the end of the operating arm away from the slider. A welding workbench is provided in the middle of the cargo box, and the welding workbench is located at the bottom of one end of the steel cage section; A folding platform is provided on one side of the cargo box. The folding platform is used to form an extended platform after being unfolded. The extended platform is flush with the bottom surface of the cargo box. The clamping claws are used to clamp the steel cage segment after the fasteners are released and drive the steel cage segment to move so that the vertical bars of the steel cage segment are aligned with those of another steel cage segment above the welding workbench.
[0008] Furthermore, several lights are installed on the top of the cargo container.
[0009] Furthermore, a ventilation system is installed on the top of the cargo box.
[0010] Furthermore, the folding platform includes several support plates that are hinged to each other, and support legs are hinged to the bottom of the support plates.
[0011] Furthermore, the welding workbench includes a tank, and the cargo container is provided with an outlet for discharging debris from the tank.
[0012] Furthermore, the vehicle body is equipped with a heater and a fan, and the cargo box is equipped with several air outlets. The air outlets are located at the bottom of both ends of the steel cage section. The air outlets are connected to pipes, and the other end of the pipes is connected to the surface of the cargo box. The heater is located inside the pipes, and the fan is connected to the pipes. The air outlets are used to generate hot air to dry and preheat both ends of the steel cage section. The air outlet is equipped with a sliding plate for controlling the concentration of hot air, and the sliding plate has several holes of different diameters.
[0013] Furthermore, the gripper includes a block, with several probes at the bottom of both ends of the block, and mechanical claws at the bottom of the probes.
[0014] Furthermore, a positioning frame is provided on the top of the block. The positioning frame includes a base, a positioning arm is provided on the base, and a clamp is provided on the positioning arm. The inner diameter of the clamp is the same as that of the vertical bar of the steel cage segment. A driving component is provided on the base to drive the positioning arm to move along the X and Z axes.
[0015] Furthermore, a diesel generator is installed on the vehicle body.
[0016] Furthermore, the side walls of the cargo box are all detachable and connectable baffles.
[0017] The technical solution of the present invention has at least the following beneficial effects: Due to the steep and rugged terrain of the mountainous area, with numerous sharp bends and undulating surfaces, a method was adopted to break the long steel reinforcement cage into multiple shorter segments. This reduced the overall length of the steel reinforcement cage, preventing it from becoming too long and hindering the vehicle's ability to turn on sharp curves. However, this also introduced a new challenge: how to subsequently re-weld the steel reinforcement cage segments in the rugged mountainous environment.
[0018] Due to the weight of the rebar cage sections, it is difficult to provide auxiliary welding equipment in mountainous and field environments, especially since multiple vertical bars of the rebar cage section need to be aligned. The positions of the two rebar cage sections to be welded together must be stable, and they need to be able to be driven to adhere tightly to ensure a good fit. Fasteners inside the vehicle body can lock the rebar cage sections during transportation, preventing them from swaying on undulating roads. Therefore, the fasteners can be directly used as fixing components for a rebar cage section during subsequent welding, ensuring the stability of the welding process. The guide rails, crossbeams, and operating arms are integrated into the top of the cargo box, assisting in loading and unloading. They also serve as driving components to align the rebar cage sections. By grabbing the rebar cage section after the fasteners are released, the position of the rebar cage section is adjusted so that it abuts against the rebar cage section fixed to the fasteners at the welding workbench, facilitating welding by the operator. This allows the rebar cage sections inside the cargo box to be removed and welded together to form a single, long rebar cage.
[0019] Because the welding of the reinforcing cage is carried out within the cargo container, the resulting long reinforcing cage, composed of multiple segments, is longer than the cargo container itself. Therefore, a folding platform is provided at one end of the cargo container, which can be extended to support the portion of the reinforcing cage that extends beyond the cargo container.

Detailed Implementation
[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0025] The following detailed description illustrates the specific implementation method: Example 1 As attached Figures 1-8As shown, a steel cage transport device for steep mountainous terrain includes a vehicle body 1, on which a cargo box 2 is mounted. The cargo box 2 is used to store several steel cage segments 4. The vehicle body 1 can be a truck or van, and the cargo box 2 is modified from the cargo box of a truck or van. The side walls of the cargo box 2 are all detachable and connectable baffles, which can be removed to facilitate loading goods into the cargo box 2. A diesel generator 16 is installed on the vehicle body 1 to generate electricity from diesel fuel to power the equipment inside the cargo box 2.
[0026] Several fasteners 3 are provided inside the cargo box 2 along the width direction of the cargo box 2. The fasteners 3 can be manual or electric buckles. After being triggered, they are engaged at the bottom of the steel cage section 4. The fasteners 3 are used to fix the steel cage section 4. Guide rails 5 are bolted to both sides of the top inside the cargo box 2. A crossbeam 6 is slidably connected to the guide rail 5. A first driving component (not shown in the figure) is provided on the guide rail 5 to drive the crossbeam 6 to slide. A slider 7 is slidably connected to the crossbeam 6. A second driving component (not shown in the figure) is provided on the crossbeam 6 to drive the slider 7 to slide. Both the first driving component and the second driving component are electric lead screws. An operating arm 8 is bolted to the bottom of the slider 7. In this embodiment, the operating arm 8 is a cylinder-driven telescopic arm. A clamping claw 9 is bolted to the end of the operating arm 8 away from the slider 7.
[0027] A welding workbench 10 is provided in the middle of the cargo box 2, and the welding workbench 10 is located at the bottom of one end of the steel cage section 4.
[0028] A folding platform 11 is detachably connected to one side of the cargo box 2. The folding platform 11 is used to form an extended platform after being unfolded, and the extended platform is flush with the bottom surface of the cargo box 2. The folding platform 11 includes several support plates 1101, which are hinged to each other, and support legs 1102 are hinged to the bottom of the support plates 1101.
[0029] The clamping claw 9 is used to clamp the steel cage segment 4 after the fastener 3 is released and drive the steel cage segment 4 to move so that the steel cage segment 4 and the vertical bar of another steel cage segment 4 are aligned above the welding workbench 10.
[0030] In practice, the long steel cage used in the project is first simulated to calculate the area of maximum stress. By avoiding the area of maximum stress, the long steel cage is divided into multiple steel cage segments 4. This makes the steel cage segments 4 shorter during subsequent transportation, requiring a shorter vehicle body, which facilitates passage through rugged and steep mountain roads and enhances the mobility of the vehicle body 1.
[0031] Fastener 3 restrains the steel bars inside the cargo box 2, preventing them from sliding and colliding during transportation, thus enhancing stability and safety. Upon arrival at the construction area, the operator needs to board the cargo box 2 and extend the folding platform 11. The folding platform 11 forms an extended platform, increasing the area supporting the steel cage and facilitating operations on the vehicle. Support legs 1102 provide support for the extended platform relative to the ground, ensuring its stability. The operator can manipulate the crossbeam 6 to slide on the guide rail 5, thereby changing the position of the operating arm 8 along the length of the cargo box 2. The operator can also manipulate the slider 7 to slide on the crossbeam 6 to change the position of the operating arm 8 along the width of the cargo box 2.
[0032] Move the operating arm 8 to any rebar cage segment 4, release the fasteners 3 on the rebar cage segment 4, and use the clamping claws 9 to fix the operating arm 8 to the rebar cage segment 4. Then, first move the rebar cage segment 4 along the length of the cargo box 2 to pull it out, and then move it along the width of the cargo box 2 to align it with other rebar cage segments 4. Then, use the operating arm 8 to drive the rebar cage segment 4 to press firmly against the other rebar cage segments 4 to ensure alignment and fit. Since the fasteners 3 on the other rebar cage segments 4 are not released at this time, it can be ensured that the positions of the other rebar cage segments 4 will not move and will not be displaced by the pushing force when the operating arm 8 drives the rebar cage segment 4 to press against it. This ensures higher alignment and fit during subsequent welding operations, guaranteeing welding quality.
[0033] Since multiple vertical bars of the reinforcing cage segment 4 need to be welded, and several welding points are obstructed by the reinforcing cage segment 4 itself, manual welding is still used. The welding workbench 10 can be recessed to provide the user with operating space to facilitate welding the lower surface of the reinforcing bars.
[0034] The welding of the reinforcing cage segment 4 is not limited to pairing two reinforcing cage segments 4. Depending on the construction requirements, users can weld three or more reinforcing cage segments 4 together to form a longer reinforcing cage. The extended platform length of the folding platform 11 is set to meet the usage length of most long reinforcing cages. In the rare cases where extra-long reinforcing bars are required, a temporary platform can be manually built for extension.
[0035] To facilitate the loading and unloading of the rebar cage segment 4, the folding platform 11 is designed to be detachable. Users can disassemble the folding platform 11 during loading to allow the rebar cage segment 4 to be loaded from the rear of the cargo box 2. The folding platform 11 can also be configured with different lengths to accommodate different rebar cage requirements during construction.
[0036] Example 2 The difference from the above embodiment is that the top of the cargo box 2 is provided with several lights 12 and a ventilation fan 13.
[0037] Since welding operations are involved in the cargo box 2, lighting 12 is installed to ensure sufficient brightness during the operation. Air exchanger 13 is used to refresh the air inside the cargo box 2 and expel gases generated during the welding operation.
[0038] Example 3 The difference from the above embodiment is that the welding workbench 10 includes a tank 1001, and the cargo box 2 is provided with a discharge port 1002 for discharging debris from the tank 1001.
[0039] The vehicle body 1 is equipped with a heater 17 and a fan 18. The cargo box 2 is equipped with several air outlets 14. The air outlets 14 are located at the bottom of both ends of the steel cage section 4. The air outlets 14 are connected to pipes 21. The other end of the pipes 21 is connected to the surface of the cargo box 2. The heater 17 is located inside the pipes 21. The fan 18 is connected to the pipes 21. The air outlets 14 are used to generate hot air to dry and preheat both ends of the steel cage section 4. The air outlet 14 is provided with a sliding plate 19 for controlling the position of hot air concentration, and the sliding plate 19 has several holes 20 of different diameters.
[0040] The function of the tank 1001 is to collect welding slag during welding operations and to provide space for operators to process the lower surface of the rebar cage segment 4. After a certain amount of welding slag has accumulated, the user can drive the welding slag debris towards the discharge port 1002 to discharge the debris.
[0041] In addition to the steep, winding, narrow, and rapid roads, mountainous areas also experience high altitudes and low temperatures, leading to significant temperature differences during welding and potentially causing substantial thermal stress. The function of the heater 17 is to generate temperature, while the fan 18 generates airflow. This airflow, passing through the heater 17, produces hot air directed towards the steel cage section 4 (the hot air is insufficient to generate high temperatures throughout the entire cargo box 2). This hot air ensures that no moisture remains in the welded section and preheats it, allowing the welded section to expand to a certain extent due to temperature changes, thus preventing excessive deformation caused by large temperature fluctuations during welding.
[0042] Pipe 21 is directly connected to the surface of the cargo box 2, allowing airflow to be injected into the pipe 21 when the vehicle body 1 is in motion. This airflow is then heated by the heater 17, directly exposing the steel cage section 4 to hot air without the need for a fan 18. Preheating is completed during transportation, allowing welding to begin upon arrival at the construction site.
[0043] The slide plate 19 can adjust the airflow. After welding is completed, the user can use the slide plate 19 to adjust the airflow and control the airflow position and size according to the temperature of the working environment, so as to control the welding cooling rate and avoid problems such as cracks and deformation caused by excessive cooling.
[0044] Example 4 The difference from the above embodiment is that the gripper 9 includes a block 901, and a plurality of probes 902 are provided at the bottom of both ends of the block 901, and mechanical claws 903 are provided at the bottom of the probes 902.
[0045] Since the welded steel cage is quite long, the clamping claw 9 needs to be designed with multiple clamping points to facilitate the translation of the steel cage. In this embodiment, four clamping points are used to reduce the difficulty of the operating arm 8 driving the steel cage segment 4 to move.
[0046] Example 5 The difference from the above embodiment is that the top of the block 901 is provided with a positioning frame 15, the positioning frame 15 includes a base 1501, a positioning arm 1502 is provided on the base 1501, a clamp 1504 is provided on the positioning arm 1502, the inner diameter of the clamp 1504 is the same as the vertical bar of the steel cage segment 4, and a third driving member 1503 is provided on the base 1501 to drive the positioning arm 1502 to move along the X and Z axes. The third driving member 1503 is driven by an electric screw on the X axis and by a multi-stage cylinder on the Z axis.
[0047] During the processing of the rebar cage segment 4, there may be processing errors, which may lead to misalignment during the alignment of the vertical bars of the rebar cage segment 4. Therefore, a alignment frame 15 is integrated into the block 901 based on the clamping claw 9. The alignment arm 1502 of the alignment frame 15 is driven by the third drive component 1503 and can move along the X and Z axes. The alignment on the Y axis is almost non-existent because it is parallel to the vertical bars of the rebar cage. The movement on the Y axis can be directly driven by the guide rail 5 to move the alignment arm 1502 along the Y axis.
[0048] The alignment frame 15 drives the clamp 1504 to move along the X and Z axes, allowing the clamp 1504 to be fixed to the vertical reinforcement bars of the rebar cage segment 4. Subsequently, by adjusting the distance of movement along the X and Z axes, it can be locked to different vertical reinforcement bars. After the clamp 1504 is locked to the vertical reinforcement bar of the rebar cage segment 4, the third driving component 1503 provides driving force, causing the clamp 1504 to bend the vertical reinforcement bar along the X and Z axes, fine-tuning the cross-sectional position of the vertical reinforcement bar, thereby overcoming machining errors of the vertical reinforcement bar.
[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
